gradle - 在 Gradle 中使用一个版本和标签发布多模块项目

Question

我在 Gradle 中有一个多模块项目，其中父 build.gradle只是子项目的聚合器，没有任何来源。

结构:

parent with version in gradle.properties
 - child1 inheriting version
 - child2 inheriting version

两个 child 都产生带有工件的 JAR，而 parent 产生空的 JAR，我根本不想在任何地方上传。

现在我想发布这样的项目。 Git 中应该有一个带有版本更新的提交和一个标签。但是，应构建所有子项目并将其上传到存储库。 我怎样才能实现它？

我试过 gradle-release plugin ，但我很难正确配置它。我得到以下任何一种:

在父级上应用插件，获得正确的提交和标记，但只上传根项目

在子项目上应用插件，正确上传项目，但每个子项目都有单独的提交和标签

我遇到了同样的问题，最后在 gradle-svn-tools 插件 ( https://github.com/martoe/gradle-svntools-plugin ) 的帮助下在 Gradle 中编写了必要的步骤。请注意，我不是 Groovy 专家，所以我想有几件事可以更轻松地完成 :)

我在父项目中的 build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'at.bxm.gradleplugins:gradle-svntools-plugin:1.6.2'
    }
}

allprojects {
    apply plugin: 'at.bxm.svntools'

    //subversion login
    svntools {
        username = svnUsername
        password = credentials.svnpwd
    }
}

//task to write the version parameter given via command line into the  "gradle.properties" files.
// Call with: gradle writeProjectVersion -PnewVersion=1.0.1-SNAPSHOT
task('writeProjectVersion') << {
    if (project.hasProperty('newVersion')) {
        //set version in gradle settings
        project.version = project.newVersion
        project.subprojects?.each {it.version = project.version }
        //set version in all the gradle.properties files
        new File(".").traverse(type : groovy.io.FileType.FILES, nameFilter: 'gradle.properties') {
            project.ant.replaceregexp(file: it, byline: true) {
                key = 'version'
                version = project.version
                regexp(pattern: "^(\\s*)$key((\\s*[=|:]\\s*)|(\\s+)).+\$")
                substitution(expression: "\\1$key\\2$version")
            }
        }
        println 'Successfully changed project version in gradle.properties to \'' + project.version + '\''
    } else {
        println 'No parameter \'newVersion\' provided, so not changing the project version.'
    }
}


//task to commit the gradle.properties changes into SVN - also needs the new version as parameter for the commit message
// Call with: gradle svnCommit -PnewVersion=1.0.1-SNAPSHOT
task('svnCommit', type: at.bxm.gradleplugins.svntools.tasks.SvnCommit) {
    if (project.hasProperty('newVersion')) {
        def files = []
        new File(".").traverse(type : groovy.io.FileType.FILES, nameFilter: 'gradle.properties') { files << it } //appends all matching files to the list
        source = files
        commitMessage = "[Jenkins Release Build] Changing project version to '" + project.newVersion + "'"
    } else {
        println 'No parameter \'newVersion\' provided, so SVN commit was not executed.'
    }
}

//task to tag the current head - also needs the new version as parameter for the commit message
// Call with: gradle svnTag -PnewVersion=1.0.1-SNAPSHOT
task('svnTag', type: at.bxm.gradleplugins.svntools.tasks.SvnTag) {
    if (project.hasProperty('newVersion')) {
        tagName = "$project.newVersion"
        localChanges = true
        commitMessage = "[Jenkins Release Build] Tagging Release version $project.newVersion"
    } else {
        println 'No parameter \'newVersion\' provided, so SVN tagging was not executed.'
    }
}

我使用 Jenkins 执行并运行以下 shell 脚本:

# execute gradle tests
gradle test
# set version in gradle.properties and tag the current code (gradle.properties changes are commited in the tag)
gradle writeProjectVersion -PnewVersion=${releaseVersion}
gradle svnTag -PnewVersion=${releaseVersion}
# build the artifacts and upload them to Nexus without running the test cases again
gradle clean build uploadArchives -x test
# set version in gradle.properties and commit the files
gradle writeProjectVersion -PnewVersion=${newSnapshotVersion}
gradle svnCommit -PnewVersion=${newSnapshotVersion}

希望这可以帮助。
